CARBURETER.

Specification of Letters Patent.

Patented June 10, 1913.

Application filed i'ieptember 30, 1912. Serial No. 723,084.

To all whom it may concern Be it known that we, STEPHEN P. Snrru and CHARLES \V. Knivnn, citizens of the United States, the said SMITH; residing at Berkeley, in the county of Alan'leda and State of California, and the said Kmvnn residing at Oakland, in the county of Alameda, State of California, have invented certain new and useful Improvements in (larl'mrcters, of which the following is a specification.

Our invention relates to that class of carbureters, intended tor use in connection with lighting plants, in which air is supplied from a suitable source. to a body of liquid hydrocarbon in a container, and brought in such relation thereto as to be carburetcd in its course to the light-burners.

The object of our invention is to provide a simple and effective carburetor of this class which is specially adapted for receiving and carbureting air in varied volume and pressures according to the number and needs of the lights, and to this end our invention consists in the novel carbureter which we shall hereinafter fully describe by reference to the accompanying drawings in which- Figure 1 a vertical section of our carbureter. Fig. 2 is a horizontal section, reduced, through the container on the line of Fig. 1 looking down. Fig. 3 is a similar section on the line i -g of Fig. 1, looking up.

1 is a container in which the liquid hydrocarbon 2, in practice, gasolene, is confined. lVithin the container is the float 3 of matcrial adapted for buoyancy in the gasolene body 2. Dependent from the under side oi the float 3 are the partition walls -t which. in practice, may be one or more strips of material preferably of metal. These walls are arranged in suitable manner to form between them an extensive continuous channel 5, as, for example, in the present illustration, as shown in Fig. 3, starting with the middle and thence continuing in successive outer increasing courses to one corner of the float 3 Where said channel opens out at 6 into the container. A good way to attach the partition strips or Walls 4: is to tack them at their outer portions to the borders of the float and to space their inner portions between strips 7 secured to the float underneath." At inte'rvals in the channel 5, we may hang ab sol-bent webbing 8 tacked up to the spacing strips 7.

9 is a guiding and leveling float for the float 3. It consists of a frame surrounding and slightly spaced from the float 3. Its top is provided with diagonal' corner rods 10 lying above the corners of the float 3 and its bottom has cross rods 11 l ving under said lioat 3. Fitted to the top of the container 1 at one side is the entrance pipe 12 which is to proceed from a suitable source of air, in practice, from an air compressor. From this entrance pipe 12 leads a flexible tube 13 which is connected at its inner end with a nipple 14, in the center of float 3, said nipple opening through the float into the beginning of the channel 5.

15 is the outlet pipe which delivers the carbureted air from the container to its destination, in practice, the pipe system of the ligbt-blu'ners.

16 is a relatively small tank connected by a nipple 17 with the bottom of the container 1, said tank having a draw-ofl' faucet 18. Into this tank 7 6 is let the filling tube 19 in which we have shown a float '20 having a rod 21 which extends upward and is used as an indicator for determining the level of the gasolene body 2 in the container 1. A cap 22 normally closes the filling tube 19.

The operation of the carburetor is as follows :-Air is supplied through the connections 12 and 13. It need only be said that the volume and pressure of this air will depend upon the number of lights used. but as the compressor or device to effect this result. forms nopart of the carburetor proper, it need not be herein illustrated. It will be suttieicnt to show that the carbureter lends itself to this action or operation. The air from the tube 13 is admitted under the [teat 3, to the beginning of the carburet-ing channel 5. It thence passes over and directly in contact. with the surface of the gasolene body 2, throughout the extensive course of said channel. During its passage itis carbureted, and is delivered from the end of said channel at 6 into the container 1 and fills the upper portion of said container, being drawn oil through pipe 15 in volume as needed by the light-burners of the illuminating system. According to the number and needs of the light burners. air under proper pressure and in proper volume will be delivered to the 'arburcter; and the float 3, it will readily be 110 air pressure,

seen, will rise relatively to the surface of the gasolene, to accon'nnodate Whatever volume is supplied, and said air will be uniformly and constantly held down by the float in contact with the gasolene, thus producing uniform carhuration. The exposure of the upper ends of the absorbent \vebbings 8 to the air will increase the carburation. The tendency of the fioat- 8 to tilt under the air pressure is corrected by the contact of the upper surface of the fioat corners with the corner rods 10 of the outer float 9, and the contact of the lower edges of the partition walls t \viththe cross rods 11 of said float 9, and thus the tloat 3 is kept level and held well. in proper position. iVhen there no the tendency of the l'loat. 23 to sink too loiv as the. Walls elmay rest upon them. The sun ll tank 16 serves three purposes. It is used to drain oil the contents ot" the container; also during operation of the appa: ratus it serves to drain oll' all water of condei sation and such water as maybe in the gasolene; and finally as a means through which to lit] the container 1 with gasolene. The t'lexibility of the tube connection 13 is to permit the tree movement of the. float 3, both in its operation under the varying airpressure, and according to the level of the gasolcne in the C'Olllttllltl'.

We claim 1- 1. A carburetor comprising a container for the liquid hydrocarbon, said container having a delivery outlet for the carlnireted air; a tloat supported by the hydrocarbon contents of said container; at second tloat surrounding but indei iendent of the first tloat and having suitable stops tor limiting the tilting movement of the first tloat; and means, For delivering the air to be carbureted directly upon the surface of the hydrocarbon under the first lloat.
